HI304N-1

Auto-Reverse Stainless Steel Cover Mini-Stirrer with Tachometer (2.5L)

$184.00

HI304N is a compact and lightweight auto-reverse magnetic stirrer with built-in tachometer and an AISI 316 stainless steel cover that supports a maximum capacity of 2.5 liters. The adjustable reverse setting stirs the sample in both directions and are ideal for applications that require a homogeneous final product and complete dissolution of powders. The stainless steel top is ideal for stirring samples that are undergoing an exothermic reaction that could damage the cover of a stirrer made of plastic or solutions containing corrosive materials. A tachometer shows the stirring speed in RPM. The stirring speed is adjustable from 100 to 1000 RPM. The HI304N stirrer requires little room which is valuable when laboratory benchtop space is at a premium.

Ideally when performing electrochemistry measurements, the sample being tested should be stirred. The use of a magnetic stirrer allows for proper mixing, ensuring that the sample is homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time for a sensor to achieve a stable reading.

Compact & Cost-Effective

The HI304N magnetic stirrer is compact and lightweight, allowing for easy handling in the laboratory environment. Limited area on laboratory benchtops is no longer a concern with this durable, space-saving stirrer. Power-indicating LED lights also assure users at a distance that the stirrer is in operation. The durable plastic covering will resist harmful effects of accidentally spilled chemicals. The HI304N magnetic mini-stirrer is cost-effective for the customer that does not need the added expense of a heating element. The advanced design incorporates electronic controls that allow the user to easily regulate the speed with great precision.

Adjustable Auto Reverse

HI304N stirrer has an adjustable auto-reverse setting. A reverse period knob allows the user to adjust the reverse interval from 30 seconds to 3 minutes. Once the interval time is set, the fluid will rotate in one direction for that amount of time and then reverse its rotation for that same amount of time, all at the desired speed in a repeated cycle until the stirrer is switched off.

Built-in Tachometer

HI304N stirrer has a built-in 4-digit LCD tachometer that shows the stirring speed in RPM for ultimate accuracy.

Stainless Steel Cover

HI304N stirrer comes supplied with an AISI 316 stainless steel cover atop the ABS body. The cover is an ideal solution for applications in which exothermic reactions occur. The AISI 316 type of steel is known to have increased resistance to chloride corrosion as well.

Speedsafe^™

Often in the lab a sample is removed from a stirrer before the speed is adequately reduced. Normally this would cause the internal motor to accelerate until it is damaged. To control the speed from changes in viscosity or removing of the load the HI304N magnetic mini-stirrer incorporates the Speedsafe^™ mechanism. With Speedsafe, a speed sensing device (opto-sensor) is coupled with an FVC (frequency voltage converter) to monitor the stirring speed. As the speed reaches a preset maximum level, the speed limiter shuts down the VCO (voltage-controlled oscillator) to slow down the motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to such a high speed that will be hazardous to both the user and the stirrer; a feature not commonly found in conventional stirrers.

Fuse Protection

For safety, in the event of a short circuit, the HI304N is equipped with a replaceable fuse. The circuitry of the HI304N is grounded to the case for additional protection
